Hi Lambert,
Thank you for posting.
I am sorry that it is happening. I will have a definite solution today. Most probably, I am on an updated trunk and that’s why I am not seeing the issue. I will be posting in next couple of hours with a solution.

Thank you
Brajesh

Hi Kyl,e
I seem to have tracked down the issue but will need a confirmation before I push the update.

1.AS I Tested, It appears that only posts displayed on the Group blog page have comments closed. The normal posts( which are not accessible from group blog screen) have no effect on the cmment status.

Are ypou facing the same issue? If yes, we need to work around over enthusiastic BudyPress comment closing filter, I had done it for BuddyBlog earlier and the same appears for Blog categories.

Can you please confirm and I will provide a quick update.

Hi Christopher,
Thank you for posting.
It is not an exploit as it will never escalate the rights of the user but still it is a bad user experience. I will have an update today. We shomehow missed this in our test and I apologize for that.

Thank you
Brajesh

Login issue should be fixed. No, It will not cause any issue as users will be added as subscribers. Please do make sure that you have set the default role as subscriber.

Hi Jay,
I have a post related to this
https://buddydev.com/buddypress/adding-users-to-the-blog-on-which-they-register-in-a-buddypress-wordpress-multisite-based-social-network/

All you need to do is change this line

$blog_id = get_current_blog_id();

to

$blog_id = 1;

rest will remain same.
